Tunnels

More value through overall performance

Tunnels are important elements of an integrated infrastructure system. Railway tunnels in urban areas are part of complex public transportation networks that may provide routes for metro, light rail or main railway lines. Rail and road tunnels help relieve congestion in city centres. Tunnels also convey water and wastewater, keeping the urban society running. Tunnels for pressurised water mains are key elements in the production of sustainable energy from hydropower plants.
